This data logger lets you save data to files on any FAT16- or FAT32-formatted SD card easily from an Arduino, which can then be read by most plotting, spreadsheet, or analysis programs. The onboard real time clock (RTC) timestamps all your data with the current time, so that you know precisely what happened when.

Overview

Adafruit’s Data Logging Shield for Arduino makes it easy to save data to files on any FAT16- or FAT32-formatted SD card in a way that can be read later by most plotting, spreadsheet, or analysis programs. The included real time clock (RTC) timestamps all your data with the current time, so that you know precisely what happened when.
